Google Earth Blog has a story about a digital earth product called Earthscape. Earthscape is a desktop program that aims to be similar to Google Earth (and others). It may end up being a decent product, but that’s not the point of this post.
At Where 2.0 last week, GEB author Frank Taylor was shown an iPhone application that uses their product. Not only does it handle the top down view (like Google Maps Mobile), but you can pan down into a 3D view! Taking it a step further, the application responds to tilting, so you can move the phone around in your hand to change the view.
The application has some work to be done before it can be released, but it shows a ton of potential. Below is the video that Frank took and you can read more about it in this blog post:
